Abstract
Method and receiver jointly detect and decode a part of an encoded, spread and modulated signal received on a channel in a wireless communication network and corrupted by channel multipath. Differences between the received signal and noiseless theoretical signals corresponding to each of the possible values of the part are calculated using hypothetical transmission matrices. The smallest difference corresponds to the actual value of the part.
Description
Technical field
The present invention relates generally to the method and receiver in wireless network, and more particularly, it relates to it is used for jointly
Detection and the technology of decoded signal.
Background technology
With personal device（Smart phone, laptop computer, tablet PC etc.）Become more commonly and frequently to make
With the needs for effectively providing service via wireless network continue to increase.About communication channel and in personal device and wireless
The rule of the structure of the message exchanged between network is in international technology group（Such as third generation cooperative partner program（3GPP））In
Reach an agreement.These rules are necessary for the device for producing various manufacturers is connectable to network.
Fig. 1 is shown for setting up the wireless system of data communication session（Such as 3GPP high-speed packet access systems）Middle basis
The example of the message that 3GPP rules are exchanged.First network device（Node B）110 on the common pilot channel to the second network equipment
120 pilot signal transmitted of user equipment (UE).UE 120 estimates channel quality based on the pilot signal for receiving（Such as noise
Than）, so as to obtain channel quality information (CQI).Using Dedicated Physical Control Channel (HS-DPCCH), also referred to as up-link control
Channel processed, to Node B report CQI together with another segment information HARQ ACK/NAK（Indicate whether received past data point
Group）.In receiving control message and when extracting CQI, channelization codes, modulation, coding etc. are distributed to UE 120 and are used by node B 110
Data communication session therebetween.Node B 110 is via shared control channel (HS-SCCH), also referred to as downlink control letter
Road, conveys this distribution information to UE 120.Once UE 120 detects the message transmitted via HS-SCCH, from node B 110
Down link data transmission to UE 120 is just started by physical down link sharing channel (HS-PDSCH).
As shown in Figure 2, it is sent to node B's 110 by UE 120 via uplink control channel HS-DPCCH
Report（Control）Message 200 is made up of a time slot for HARQ-ACK and two time slots for CQI, as shown in Figure 2
Go out.When UE is in non-MIMO（Multiple-input and multiple-output）When being configured with single carrier in pattern, 10 are encoded into by 1 of HARQ-ACK
To transmit in the first slot, and 5 of CQI are encoded into 20 to be sent to node B in latter two time slot.Report
The message of HARQ-ACK and channel quality information is not only sent when data communication session is set up, and in ession for telecommunication periodically
Ground sends.
Conveyer 300 is shown in Fig. 3（For example in UE 120）Block diagram.In frame 310, using predefined code
This, the position of HARQ-ACK is encoded into 10 by the code book for such as illustrating in 25.212 version 11.7.0 of 3GPP TS.In frame
In 320, using the block code such as described in 25.214 version 11.9.0 of 3GPP TS, by 5 of CQI（Search from using
The signal to noise ratio that table quantifies is obtained）It is encoded into 20.
Then, in frame 330,10 of the HARQ-ACK of coding are combined, modulate, using 256 with 20 of the CQI of coding
Spreading factor extend and scrambled to generate the individual chips of 7680 (=256x30) with the specific scrambling code of cell.7680 chips
Node B is sent in transmission interval of the single time (TTI).
General receiver 400 is shown in Fig. 4（For example in node B 110）Block diagram.In frame 410, via one
The signal that individual or multiple antennas are received is descrambled, de-spreads（de-spread）And demodulate.Frame 410 includes Minimum Mean Square Error（MMSE）
Detector, " rake " that be configured to reduction multipath fading（Or " grake "）Balanced device, descrambler, despreader and demodulator.Will
It is noted that signal can be balanced after it is descrambled and de-spreads.Then distinguish decoded signal respectively in the frame 420 and 430
HARQ-ACK and CQI parts, to retrieve 1 of ACK/NAK and 5 of CQI.
General receiver has as a drawback that：Block is individually processed, and this knows from signal detection theory and do not fill
Point, cause the Block Error Rate of suboptimum（BLER）.Due to such report message Jing often exchanges between mobile device and network equipment,
It is therefore desirable for the information for optimally retrieving carrying in the receiver with minimum possibility mistake and repetition.
The content of the invention
